Which consequence results when rapid aggradation overwhelms river levees?

💡 Explanation

Floodplain lateral migration speed increases because sediment deposition exceeds levee height; therefore, the river cuts laterally, rather than increasing channel depth, and does not directly impact bedrock weathering.
